Seasoned Unix admins may already know the pitfalls of blindly running

careful when using it.

This article shows some techniques on how to cause ldd to run arbitrary
code, and how easy it is to trick a sysadmin into executing that code as

This is an old exploit, but is shown to still be usable today. It is
recommended not to run ldd as root, use objdump instead, or, if you need
to use it anyway, run as a non-privileged user.

"objdump -p ./program | grep NEEDED"
